The present invention relates to machines 10 of the Gritzn'cr type, for stitching shoe soles.

necting such operating member to a power driven actuating member. machine to operate it by foot or other In the art to which the present invention power, as difi'erenti ited from hand power; relates, there is at present on the market and the main point in the invention lies in 'a hand operated. sole stitcher, known as the the way which I h wediscovered for con- Gritzner, which is a very cheap and simple vcrting this niachim from a hand operated machine, but which is open to the serious ty )0. to a foot or otl or power operated type-( nt objection of being diliicult to manipulate by To the pin 161' :ttach an arm 17, which a hand operated method. I have found that in turn is connected to astudlS on a fly by a very simple mcansl can operate this wheel or disk 15). This'latter constitutes type or' machine with a power mechanism, a power driven acnuating member for the and this without disturbing in any way the mechanism, and in the construction shown arrangement or construction of the operatis actuated by a belt 20 extending from a. ing parts of the present Gritzner machine. pulley 21, which is operated by means of Referring how to the drawings, the a foot treadle 22 and a connecting arm 23, stitclier is designated by the general 1111- although the precise means of operating the moral t.

foregoing, however; is a'cheap and practical method for operating this power driven actuating member 1.9.

It willbe, from the foregoing description that by the foot of theoperator, it will drive the belt 20, rotating the flywheel or disk 19, which will. impart a reciprocating move'- ment.to;,tl1e link 17 and move the reciproeating member Shack and forth, thus operating the machine, and that by. so operat ing it, the user has both hands free for holding and tlirning the shoe. It is also apparent that, so far as the mechanism for operating the needle and for placing ten- 5am on the thread are concerned, these are not altered or changed in the leastby )roiding the present im"rovement.- In iact, the machine remains i aithetreadle 22 is rockedentical, with the ex described. cept-ion that by a simple addition it is operi ated by power other than hand, thus expediting the use of the machine.

I claim:

A sole stitcher of prising a table, a horizontally reciprocating operating member above the table, thread feeding mechanism and needle mechanism actuated byisaid operati ng member, a caslng carried by the table in which said operating member moves,

said casing having a slot foi'med therein, said slot extending parallel with the direction of movement of the reciprocating member, a pin connected to the operating member and extending through said slot to a point beyond the outer wall of the casing a power driven member, and a coi-ncction between said pin and power driven member, substantially as MATHEW SOENS.
